Abstract
A valve extension tool is configured to operate a hand wheel of a valve. The valve extension tool includes a handle configured for operation by a first operator and a pipe assembly connected to the handle. The pipe assembly includes a proximal pipe segment connected to the handle, a crank connected to the proximal pipe segment and configured for operation by a second operator, and a distal pipe segment connected to the crank. In addition, the valve extension tool includes a front pipe segment connected to the distal pipe segment of the pipe assembly. Further, the valve extension tool includes a joint connected to the front pipe segment, wherein the joint is configured to engage a hand wheel of a valve.
Claims20
A valve extension tool, comprising:
- a handle configured for operation by a first operator;
- a pipe assembly connected to the handle, the pipe assembly comprising:
- a proximal pipe segment connected to the handle,
- a crank connected to the proximal pipe segment and configured for operation by a second operator, and
- a distal pipe segment connected to the crank;
- a front pipe segment connected to the distal pipe segment of the pipe assembly;
- and
- a joint connected to the front pipe segment, wherein the joint is configured to engage a hand wheel of a valve.
A valve extension tool, comprising:
- a wheel handle configured for operation by an operator;
- a pipe connected to the wheel handle;
- and
- a joint connected to the pipe, the joint comprising:
- a center support with a center hole through which the pipe passes, wherein the pipe is welded to the center hole of the center support, and
- a pair of hand wheel forks welded to an internal surface of the center support, wherein the pair of hand wheel forks extends toward the valve and is configured to engage a hand wheel of the valve.
A method for operating a hand wheel of a valve by a valve extension tool, comprising:
- selecting, based on a required distance from the valve to a first and a second operators operating the valve extension tool, a front pipe segment with a corresponding length;
- connecting a handle and the front pipe segment to a first and a second ends of a pipe assembly, respectively;
- connecting a joint to the front pipe segment;
- holding, by the first operator, the handle to have the valve extension tool engage the hand wheel of the valve;
- and
- rotating, by the second operator, the hand wheel of the valve by rotating a crank of the pipe assembly.
